In the final years of the Dayin Dynasty, the spiritual veins ran dry, demons and monsters wreaked havoc, and the Mystic Sects fell into decline. The few sects that remained struggled to maintain order in the mortal world with incomplete arts. Legend has it that the ancient Mystic Sect scripture, The True Explanation of Earthly Fiends, records seventy-two divine abilities. Gather them all, and the spiritual veins can be restored. But because of the backlash they cause, the abilities were split apart and sealed within demons and monsters, becoming the main prize in the struggle between cultivators and their foes. Shen Yan, the last disciple of the fallen Mystic Sect Qingyun Sect, was born with clear spiritual apertures, yet could not cultivate conventional arts. Patient and resilient, he carried the sect's blood feud. By chance, he obtained a fragment of The True Explanation of Earthly Fiends. To unlock each divine ability, he must slay the corresponding demon or monster, and every time he uses an ability, he suffers the backlash of its lingering soul.
